摘要
哈日根台银锌铜多金属矿床位于大兴安岭西坡铅锌银多金属成矿带之沙不楞山铜铅锌成矿带内,受东西向的米生庙复背斜次一级的近南北向断裂构造控制.矿(化)体赋存在构造破碎带内,由石英细脉和网脉构成,总体呈脉状或似脉状,具有分支复合现象.对矿石的矿物组成、结构构造特征及类型研究表明,金属矿化与硅化、钾长石化、萤石化等蚀变作用有关.矿床的形成与侏罗世花岗岩浆活动有密切关系,成因类型为岩浆热液型.
The Harigentai Ag-Zn-Cu polymetal deposit, located in the Western Daxinganling Pb-Zn-Ag polymetal metallogenic belt, is controlled by the secondary S-N-trending fault of the E-W-trending Mishengmiao anticlinorium. The ore/mineralized bodies, occuring in the structural fracture zones, are composed of quartz veinlets and networks in complex style. The mineral composition, structures and types of ore are studed. The results show that the mineralization is related to silicification, K-feldspathization and flouritization. The forming of the deposit is on intimate terms with the Jurassic granitic magmatism. The genesis of the deposit belongs to magmatic hydrothermal type.
